1 Claim.

Our invention relates to a combined feeder and cutter for roll paper andthe principal object of our invention is, to provide a relativelysimple, practical and inexpensive extension paper cutter f 5, that maybe conveniently employed for feeding the free end of a roll of paper toa point within easy reach of the operator in cases where, due to theconstruction of the counter or show case, it is necessary to locatetheroll of paper upon or 10, near the floor. Y

The invention herein disclosed is an improvement on the constructionsforming the subject matter of co-pending patent applications filed byJames W. McClintock as follows: Roll paper outlter, sled March 22nd,192s, seria No'. 263,637, patented March 24, 1931 as Patent No.1,797,432; Roll Paper Holder, filed January 16th, 1929, Serial No.332,990, patented Jan. 5, 1932 as Patent No. 1,840,120; Roll PaperCutter, filed April 22nd,

20, 1929, Serial No. 357,113, patented June 28, 1932 as Patent No.1,865,399.

Further objects of our invention are, to generally improve upon andsimplify the existing forms of extension roll paper feeders and cuttersand particularly the constructions disclosed in the above mentionedco-pending patent applications and further, to provide a device of thecharacter referred to that is very compact so that it occupiescomparatively littley space when positioned for use on a show case,counter or the like and further, to provide an extension roll paperfeeder and cutter having convenient and easily manipulated means foreffecting a positive feed for the end of the web of paper that passes Vthrough the device.

` With the foregoing and other objects in view,

our invention consists in certain novel features of construction andarrangement of parts that will hereinafter be more fully described andclaimed and illustrated in the accompanying drawings, in which:

Fig. 1 is an end elevational view of an extension roll paper feeder andcutter constructed in accordance with our invention.

Fig. 2 is a front elevational View of the combined feeder and cutter, A

Fig. 3 is a vertical section taken approximately on the line 3 3 of Fig.2.

Fig. 4 is a vertical longitudinal section taken approximately on theline 4 4 of Fig. 1.

Fig. 5 is a cross section taken approximately on the line 5 5 of Fig. 2.

Fig. 6 is an elevational view of the extension roll paper feeder andcutter positioned for use on the rear of `a counter or show case andwith the ing member, for instance, the rear wall of a show case orcounter and which plates serve as supports for the operating parts ofthe device. The

lower portions of these end plates are connected by a substantially Zplate or bar 11, the ends thereof being secured in any suitable mannerto ears or flanges 12 that project inwardly from the lower portions ofthe end plates.

Formed integral withor fixed to the outwardly projecting portions of theend plates 10 are inwardly projecting tubular members 13 and extendingthrough these tubular members and arranged for rotation therein areshort spindles 14 and secured to the inner ends of the latter are discheads 15.

. Arranged between the end plates is a paper feeding roll 16, preferablya metal tube and this tube is secured to the heads 15 in any suitablemanner, preferably by indented portions 17 and thelwall of said rollerand short indented portions project into notches 18 that are formed inlthe heads.

The external surface of roller 16 is roughened or coated with rubber orrubber composition in order to produce a frictional surface.

At one end of the roller the `wall thereof is provided with a series ofratchet teeth 19 and adapted to engage these teeth is a detend 20 thatis pivoted on the adjacent end plate 10.

Journaled in an axial bore 21, that is formed in each spindle 14, is apin or shaft 22 and secured to the outer end thereof and positionedbeyond the outwardly projecting portion of the end plate 10 is a smalldrum 23.

Secured to the periphery of this drum is one end of a ribbon spring 24,the opposite end thereof being secured to a manually operable frame, aswill be hereinafter more fully described.

Fixed on the outer end of spindle 14, within the drum 23, is a ratchetwheel 26 that is engaged by a spring pressed pawl 27 and the latterbeing pivotally mounted on the drum.

Formed integral with the circumferential wall of drum V23 is a finger 28that projects through an arcuate slot 29 in the outwardly projectingportion of the end plate 10 and engaging the inner end of this linger isone end of a coiLspring 30,

which latter surrounds the tubular member 13 and the opposite end ofsaid spring being secured to the inner end of said tubular member.

The manually operable frame or handle that is utilized for impartingrotary movement to the paper feeding roller 1 6 comprises a pair of endplates 31 that occupy positions adjacent to and parallel with theoutwardly projecting portions of the end plates 10 and these plates 31are provided with notches 32 for the accommodation of the drums 23.

The lower inner ends of plates 31 are secured to the ends of a shaft 33and the latter is journaled in ears 34 that project downwardly from therear portions of plates 10.

Projecting outwardly and upwardly from the upper forward portions ofplates 3,1 are short arms 35 and secured thereto are the ends of a rod36 that functions as a handle and which is manually engaged when thepaper feeding operation takes place.

The outer ends of the ribbon springs 24 that pass around the drums 23are connected to pins 25 that project inwardly from the outer portionsof plates 3.1 (see Fig. 3).

Formed in the outwardly projecting portions of the plates 10 andconcentric with the axis of rod or shaft 33` are arcuate slots 37 andprojecting therethrough are. short fingers 38 that are formed integralwith the lower rear portions of the, plates 3 1.

The construction just described serves to limit the outward swingingmovement of the frame comprising plates 31 and rod 36.

Arranged between the outwardly projecting portions of the end plates 10is a cover plate 39 that is shaped so as to` cover the front and top ofthe. feed roller and the lower portion of the front wall of this coverplate is extended outwardly at a slight angle relative to a verticalplate and the lower edge of this inclined portion is sharpened in orderto form a paper tearing edge 40. The lower portion of this cover plateis suitably hinged, preferably by means of rivets 41 to the lower frontportions of the outwardly projecting members of end plates 10.

Secured on the inner face of cover plate 39 are flat springs 42, thefree ends of which bear with yielding pressure against the surface ofthe paper v' that passes over the feeding roller 16 (see Fig. 5).

Secured to the upper rear portion of cover plate 39 and projectingoutwardly therefrom directly over the rear portions of endplates 10 arefingers 43 which may be engaged to swing the cover plate outwardly forthe purpose of threading or arranging the end of the web of paper overthe feeding rollerA 16.

In order to thread the webof paper through the combined feeder andcutter, rod 36 is engaged and swung outwardly and downwardly to itslimit of movement and cover 39 is now swung outwardly and downwardly soas to rest on rod 36, thereby holding the latter andthe end plates 31 intheir outwardly shifted positions. When the parts are thus/shifted thefeeding frame occupies the position as shown by solid lines in Fig. 6and the cover plate occupies the position shown by dotted linesof saidfigure.

The web of paper. is now drawn upwardly behind the Z bar 114 and to therear of the feeding roller 16 and the end of the web of paper is broughtover the roller and downwardly in frontv of the same.

Cover plate 39 and the frame comprisingharndle l 36 and end plates 31are now restored to their normal positions and the device is ready foruse.

When a portion of paper is torn from the web that passes through thedevice the end of the paper occupies a position immediately behind thetearing edge 46 that is formed on the lower edge of the wall of thecover and in order to feed outward and downward a sufficient amount ofpaper would be grasped between the thumb and ngers so` that the desiredportion of paper may be un wound from the roll, the operator engageshandle 36 and swings the f same outwardly and downwardly to its limit ofmovement, as shown by solid lines in Fig. 6. v

As this movement takes place the ribbon springs 24 that are connected toend plates 31 impart rotary motion to the drums 23 and through pawls 27and ratchet wheels 26, this rotary motion is imparted to. spindles 14and which latter are connected through heads 15 to feed roller 16.

As the feed roller is thus positively rotated and as the web of paper isin engagement with the. frictional surface of said roller, said web oflpaper will be movedso that its, end portion will be prof. j ected ashort distance below the tearing edge 40.

As the feeding frame comprising handle 36. and end plates 3.1 isactuated as just. described springs 30 which are connected at theirouter ends to thedrums 23, will be partially wound, thereby storingtension therein and upon the release of the feedingv frame the tensionof said spring-s. 30: will reversely rotate the drums 23, therebyrewinding the ribbon springs 24 thereon and returning the feed-. ingframe to its, normaly position. During this operation the points ofthepawls 2'7 ride over the ratchet teeth` 26. During this return ofthefeedfA ing frame andV the drums to their normal posi. tions, thefeeding roller is. held against reverse ro tation by` detent 20 that`engages the` teeth 19; on, the end of the feeding roller.

After a short portion of the end of the; weby of paper has been feddownwardly and outwardly below the cutting edge 40, as just described,the. operator engages theprojecting portionA of the paper u with thethumb and: ngers and exerts suflicient 126 pull'to. unwind a portion ofthev paper from the roller and which paper passes overl roller-f 16,thereby rotating the same so as to forma rollingsupport for that portionof the paper that is withdrawn and during this rotation ofthe roller theratchet teeth 19 ride past the point of detent 20- andthe teethofratchetwheel 26 ride past detent 27.

When the desired amount of paper has thus s been unwound from` the rollandfdrawn, through 130 the combined feeder and cutter the operator pullsthe withdrawn portion ofthe paper upwardly with a quickmovement'against' the cutting edge 40, thereby severing the web. of`paper on a straight transversely disposed line and the portion ofj paperthus out fromthewebis now used for wrapping purposes.

Any tendency of that portion of the enolA of thev web of paper betweenthe roller and the cutting edge 40 to buckle or curl upwardly, withinthe`- housing is resistedby the flat springs42 that bear on that portionof the web of paper that overlies. the front side of the roller andthusk the end.v of the web of paper is retained in properv position fordownwardmovement upon the successive operation of the feeding means.

Thus it.A will b e seen that Wevhave provided a combinedy paper feederand cutter thatis rela-f. tively simple in construction, APositive inoperation;V ma
